你没有指定你正在使用的语言。根据语言支持的正则表达式工具，它可能是可行的。例如，在Python中，它可以通过以下方式完成：

import re

text = 'John Paul ...'

def do_replacement(m):
    global match_number

    match_number += 1
    return f'Name{match_number}'

# Reset match_number:
match_number = 0

# As an example, match text on a word boundary starting with a
# a capital (English) letter followed by zero or more lower-case letters:
new_text = re.sub(r'\b[A-Z][a-z]*\b', do_replacement, text)
print(new_text)

图纸：

Name1 Name2 ...

在PHP中：

<?php
$text = "John Paul ...";

$match_number = 0;

$new_text = preg_replace_callback(
    '/\b[A-Z][a-z]*\b/',
    function ($matches) {
        global $match_number;
        $match_number += 1;
        return "Name$match_number";
    },
    $text
);

echo $new_text;
